Yan created SPARK-3306: -------------------------- Summary: Addition of external resource dependency in executors Key: SPARK-3306 URL: https://issues.apache.org/jira/browse/SPARK-3306 Project: Spark Issue Type: New Feature Components: Spark Core Reporter: Yan
Currently, Spark executors only support static and read-only external resources of side files and jar files. With emerging disparate data sources, there is a need to support more versatile external resources, such as connections to data sources, to facilitate efficient data accesses to the sources. For one, the JDBCRDD, with some modifications, could benefit from this feature by reusing established JDBC connections from the same Spark context before. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
